与GitHub操作有关的事件

在2026年7月19日23:05 UTC至2026年7月20日03:55 UTC期间，Actions自托管及大型运行器无法连接至GitHub。在此期间，尝试获取运行器时，Actions作业出现延迟或失败。使用标准及Mac托管运行器的作业未受影响。受影响运行器的重连流量也增加了GitHub API的负载，导致平均请求延迟额外增加3-4秒，并出现5xx错误率升高的情况。<br /><br />此次事件由内部服务子集中的证书生命周期管理故障引起，导致SSL证书过期，从而中断了运行器的连接。我们通过轮换受影响的证书恢复了服务。恢复工作于02:45 UTC开始。至03:55 UTC，排队的作业积压已处理完毕，工作流延迟率恢复正常。<br /><br />为防止再次发生，我们正在加强证书续期自动化，增加备用过期监控与告警，并改进运行器API中断期间的断路器保护，以降低对其他API的级联影响风险。

原文Between July 19, 2026, at 23:05 UTC and July 20, 2026, at 03:55 UTC, Actions self-hosted and larger runners were unable to connect to GitHub. During this period, Actions jobs were delayed or failed when trying to acquire a runner. Jobs using standard and Mac hosted runners were not affected. Reconnection traffic from affected runners also increased load on GitHub APIs, resulting in 3-4 seconds of additional average request latency and elevated 5xx error rates. <br /><br />The incident was caused by a certificate lifecycle management failure in a subset of internal services, resulting in an SSL certificate expiration that disrupted runner connectivity. We restored service by rotating the affected certificate. Recovery began at 02:45 UTC. By 03:55 UTC, queued workflow backlog had been processed and workflow delay rates returned to normal.<br /><br />To prevent recurrence, we are strengthening certificate renewal automation, adding fallback expiry monitoring and alerting, and improving circuit-breaker protections during runner API disruptions to reduce the risk of cascading impact to other APIs.
